Wait for maven to finish deploying during test
What does this MR do?
The test builds a maven package in a docker container. The build process can take too long depending on how long it takes to download all the dependencies and build.
There is an issue open to improve the test, but for now we make it wait up to 5 minutes to build and deploy. We stop the container as soon as deployment is complete so that it doesn't wait the full 5 minutes.
We also force delete the temp directory used to store the source for the package because it seems to take some time for docker to release the files after the container is stopped.
